The correct option is A Sher Shah Suri
Sher Shah started the Suri dynasty in 1540 by defeating Humayun. He was one of the greatest administrators of medieval India. During his rule, he introduced Dam- small copper coin, Mohur, the gold coin and Rupiya the silver coin. His silver rupee coins weighed 180 grains, of which 175 grains were pure silver. Sher Shah’s name and title and place of mint were invariably inscribed on the coins in Arabic characters.
